mrnovnn rwx ron MANUFACTURIRG- STEEL.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, JACOB J AMESON, of Philadelphia, in the county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Fluxes for Manufitcturing Steel and 1 do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters lndicating like parts wherever they To enable others skilled in the art, to construct and use my invention,.I will proceed to describe it.

My invention relates to fluxes for use in the manufacture of steel; and

It consists in a new compound of ingredients to form a flux.

In the man ufact-ure of steel from castiron,or from a mixture of cast-iron and ore, I have ascertained that the process can be much improved and expedited by the use of a new flux, made of the following ingredients, viz:

Silex, about forty parts.

Black oxide of manganese, four parts.

Nitrate of soda, ten parts. Red clay, thirty parts. Powdered charcoal, in bulk, equal to one-fJurth of the'quantity of iron or iron and or used. The furnace is charged as usual, and the above-described composition is added as a flux.

The charging of the furnace add its management,

having been fully described in the patents heretofore granted to me, need not be herein described.

By the'use of the flux above described,'I am able 0 produce a good quality of steel direct from pigmetal alone, or from pig-metal combined with a proportion of raw ore, in a very cheap and expeditious manner.

Having thus described my invention, What I claim, is-

The herein-described composition, manufacture of steel.
